Purpose: To evaluate retinal and choroidal changes in patients with internal carotid artery stenosis who had undergone carotid artery stenting or endarterectomy. Methods: The study included 43 patients with internal carotid artery (ICA) stenosis that required stenting or endarterectomy and 40 healthy controls. Patients were divided into two groups according to the degree of stenosis evaluated by magnetic resonance angiography. Group 1 consisted of patients having ICA stenosis of 50 to 70%, and Group 2 has more than 70%. Enhanced depth imaging optical coherence tomography (EDI-OCT) was used to measure the retinal thickness (RT) and choroidal thickness (CT) in all subjects before surgery and at 1, 3, and 6 months after surgery. Results: Subfoveal and parafoveal CT were significantly lower in patients with ICA stenosis than the control group (p <.05, respectively). Patients with 50-70% stenosis had a significant increase in the CT at 1, 3, and 6 months after ICA stenting or endarterectomy (p <.05). Patients with >%70 stenosis did not have a significant increase in the CT at any time after ICA stenting or endarterectomy. Retinal thickness was not statistically different between the patients with ICA stenosis and the control subjects, and RT showed no significant change in patients with ICA stenosis before and after the surgery. Conclusion: Choroidal thickness was significantly thinner in patients with internal carotid artery stenosis. ICA stenting provided a recovery in the choroidal thickness in patients with moderate to advanced stenosis. [ABSTRACT FROM AUTHOR]

6-year-old boy with a complaint of blurred vision for two months was referred to our clinic. His visual acuity was 20/32 in the right eye and 20/20 in the left eye. Optical coherence tomography (OCT) revealed optic disc pit maculopathy in the right eye. The patient was followed for 6 months without any treatment. At the end of the 6-month period, the patient's visual acuity was 20/20 in both eyes. The OCT imaging showed spontaneous regression of the optic disc pit maculopathy. In this case report, it is concluded that in children, spontaneous regression of the optic pit maculopathy with full recovery of visual acuity is possible. The development of optic pit maculopathy in childhood is rare and there are not enough studies on the treatment methods. Therefore, our case report may be helpful in the management of similar cases of pediatric optic disc maculopathy. [ABSTRACT FROM AUTHOR]

Background/aims To investigate the effect of smoking on choroidal thickness using Fourier domain optical coherence tomography. Methods 17 otherwise healthy smokers (study group) and 17 non-smokers (control group) were enrolled. In the study group, all participants underwent optical coherence tomography scanning at baseline, and 1 and 3 h following smoking one standard cigarette. Also the participants of the control group underwent optical coherence tomography scanning in the morning which was followed by two further examinations at the first and third hours, respectively. Choroidal thickness measurements were performed. Results The mean choroidal thickness at the fovea prior to smoking was 301.1±63.1 μm, which decreased to 284.2±56.7 μm at 1 h and 270.8±80.0 μm at 3 h following smoking ( p=0.001). The mean choroidal thickness was significantly decreased following smoking at all five extrafoveal points. The difference in choroidal thickness was not statistically significant at 1 and 3 h of smoking at all six points. In the control group, the mean baseline choroidal thickness at the fovea was 270.6±57.9 μm, which was 272.5±52.4 μm at 1 h and 273.8±57.4 μm at 3 h (p=0.816). Conclusions Cigarette smoking causes a significant decrease in choroidal thickness following smoking. Fourier domain optical coherence tomography can effectively demonstrate choroidal thickness.

Summary To report an outbreak of Fusarium solani endophthalmitis after uneventful cataract surgeries performed on the same day in the same operating room. Nine patients underwent phacoemulsification at 4th Clinic of Beyoglu Eye Training and Research Hospital in Istanbul. Cefuroxime axetyl was injected intracamerally from the same vial to all patients at the end of surgery. All patients developed acute postoperative endophthalmitis. Presentation, cultural studies, treatment, clinical responses and risk factors were evaluated. Cultural and DNA sequence findings revealed F. solani. Antifungal therapy was begun and pars plana vitrectomy, intraocular lens and capsule extraction were performed. Corneal involvement was correlated with old age and systemic disease. Fusarium solani should be considered in acute postoperative endophthalmitis. This infection can be controlled with early and aggressive combined antifungal and surgical treatment. The patients with corneal involvement had poor prognosis. It is important to use solutions prepared separately for each patient. [ABSTRACT FROM AUTHOR]

This case report evaluates a 38-year-old male patient with retinal injury and visual impairment due to the exposure of Class 3A handheld greenblue diode laser purchased online. The patient, who was unresponsive to medical treatment, developed a full-thickness macular hole over time and required vitreoretinal surgery. Although the patient had an anatomical and functional improvement by early surgical treatment, it should be noted that these devices have the potential to cause permanent damage to the eye. If unlimited access to high power handheld laser devices continues, this will continue to be a significant global public health problem, leading to a large number of eye injuries.
